Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.Has the printer been disused for a considerable period of time, or alternatively, had its black ink only been used for a considerable period and the color ink never used ?That would explain the color not showing up.When you do a test print, e.g. a Nozzle Check, etc., does any color show up at all ?

I'm sorry, I was attending to another case.Did you remove the orange protective tape on those new cartridges?Are they properly locked into place?Are they genuine HP-OEM-original cartridges, or are they refilled, or 'compatible' ?
